Figure 2. Chromate Induces Apoptosis and Karyorrhexis.

Bright field microscopy pictures taken of lung sections obtained from mice at 24 hrs post-intranasal exposure to 50 µL of 1.2 mg/mL basic zinc chromate suspended in saline. Sections were stained with Giemsa and images were taken at an original magnification of 40×. A) Cells in the airways of chromate-exposed animals exhibit apoptosis (red arrows) and karyorrhexis (circled). B) Cropped 40× original magnification of the boxed region in A.
